Adjust idle on Mack 673?

[jjmartinez1982]

I’m trying to find the spot in the TMs where it shows how to adjust the idle on the diesel engine but I’m coming up with nothing! Does anyone know how to do this? Current idle speed is just at 500 rpm.

This did the trick. Found the info I needed! I appreciate it.

It should be between 550 and 650 rpm for a 673 if I remember correctly.

I set it (using the stock tach) to 590-610 more or less. Idles much better now.
